My trick was using Kind granola clusters as the topping, along with a little honey. That saved me from needing butter and flour to make the topping. I also used some corn starch and honey instead of sugar and flour in the filling and it worked perfect. Since the topping was also already crunchy, I only had to bake this for about 20 mins vs the typical 30-40 mins...which make it even better.
Clean Eating Peach Crumble
Makes 4 servings
-- 8 small/medium peaches
-- 2 tsp corn starch
-- 1 tsp almond extract
-- Kinda granola clusters (I used the Vanilla/Blueberry clusters)
Preheat your oven to 350. Then, dice your peaches and toss with the corn starch, a little honey and the almond extract. Place in a greased pan. Top with the granola until it evenly covers the top (this could be 1-2 cups depending on the size of your dish). Then drizzle some more honey on top of the granola and baked for 20 mins or until the peaches are bubble and the top is browned. Then enjoy, or cover with whipped topping (NOT CLEAN) if you are my husband. Oh well I tried...ha! It's still very good even without whipped topping, just a FYI :)
